Use when reverse-engineering or detecting malware — static triage + capa/YARA-X, emulation/DBI/.NET unpacking, dynamic/fileless/Volatility 3 memory analysis, C2 config extraction (Cobalt Strike/CAPE), C2 traffic detection (JA4+, beaconing).
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Malware Analysis ## When to Activate - Triaging an unknown binary/script: identity, packing verdict, capability map, IOCs, go/no-go for detonation. - Recovering the real payload from a packed/crypted/obfuscated loader (commodity loaders, RAT chains, .NET). - Detonating safely and recovering **fileless / in-memory** artifacts (injection, AMSI/ETW patching, WMI persistence). - Extracting malware configuration (C2, keys, sleep/jitter, campaign IDs) for threat intel and detection. - Detecting/characterizing C2 on the wire (beacon cadence, JA4+ fingerprints, tunneled/DoH channels). - Writing durable, low-FP YARA-X detection from analysis findings; incident-response scoping. ## Technique Map | Technique | ATT&CK | CWE | Reference | Script | |-----------|--------|-----|-----------|--------| | Hash/imphash/Rich/ssdeep/TLSH triage + PE anomalies | T1027 | CWE-506 | references/static-triage-capa.md | scripts/triage.py | | Per-section entropy + packer/RWX/EP heuristics | T1027.002 | CWE-1066 | references/static-triage-capa.md | scripts/triage.py | | Obfuscated string recovery (FLOSS) | T1140, T1027.013 | CWE-656 | references/static-triage-capa.md | scripts/triage.py | …

How to install
mdr add hypnguyen1209/offensive-claude/malware-analysis@sha256:5106ffb534cfdd49The line at the top of this page pins the label git:20260629.9f4a1a5, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
